When Sarah Lance instinctively beats up a thug in the mansion and asks Oliver how she could possibly know kung fu (not knowing she's in the Dominator VR), Oliver says she most likely used Jeet Kune Do (which the late Bruce Lee created prior to his death). Despite the nonfiction reference to Bruce Lee's style, the League Of Shadows has been in existence for centuries in Nanda Parbat, Tibet and it is highly unlikely they would have adopted Lee's Jeet Kune Do (which he created in the West) and was considered a controversial style at the time of its introduction. It would be more consistent with Arrow continuity if Oliver surmised Sarah had used Wing Chun considering Team Arrow members have been shown training on the WC wooden dummy and this style was created in the late 18th century in China, thus allowing the LoS ample time to assimilate the style.
